CULTIVATOR.

Application filed April 25, 1918, Serial No. 93,402. Renewed'July 12, 1923.

My invention relates to tillage machines and more particularly to the type known as two row eultivators, and the object of my invention relates to the lateral adjustment of the gangs of cultivating devices and to certain means. employed to guide the machine by angling the supporting wheels as will be more clearly set forth in the following specification.

' Referring to the drawings in which similar numerals indicate identical parts Figure 1 is a plan view of a two-row culti vator having my improvements embodied therein. Figure 2 is a side elevation with the wheels removed. Figure 3 is a front elevation of one end of the machine. Figure 4 is a rear elevation of part of the machine. Figure 5 is a plan view of part of the cultivator showing in dotted lines the position of the main frame when the wheels are angled. Figure 6 is a detail side elevation of the gang beam adjusting lever and connected parts. Figure 7 is a detail plan view of the bell cranks by which the gangs are adjusted laterally. Figure 8 is a sectional detail of part of the support of the forward end of a gang beam. Figure 9 is a detail plan of one of the master levers and connections, and Figure 10 is a side elevation thereof.

A main frame consists preferably of two channel bars 1 and 2 having their ends curved and joined and secured firmly together by castings 3 bolted to both bars. Integral with the castings 3 are sleeves 4 forming hearings in which are journaled Vertical spindles 5 forming part of crank axles 6 which are bent to extend rearwardly from the spindles 5 and are then bent outwardly to form hori zontal spindles 7 on which are mounted supporting wheels 8. Rigidly secured centrally on the main frame is a seat support 9 composed preferably of two fiat parallel bars spaced apart and extended forwardly of the main frame to form a supporting means for g a draft device. On the rear of the support 9 is fixed a seat 10.

On the upper ends of the spindles 5 are 1 rigidly secured rearwardly extending arms 11 connected with each other by a transverse rod 12; centrally on the rod 12 is secured-a casting 13; between the bars of the seat support 9, adjacent the frame bar 2, is a casting i l in which is journaled the central vertical portion of a crank member 15. which is bent rearwardly above and below the casting 14,

the upper rcwardly extending portion having a vertical termination which is journaled in the casting 13 on the rod 12.

The lower rearward extension ofthe crank member 15 has preferably intcgral'therewith laterally extending arms 16 on the free ends of which are secured foot rests or treadles 17.

The gang beams are supported on the frame 1 in the following manner; the beams are constructed of bars 19 and .20 spaced apart at their rear by braces 21 bolted thereto, and converge forwardly to couplings 22 to which, they are secured. The gang beams are arranged in pairs and are connected to and spaced apart by vertically disposed yokes 23 and 23 having their free ends bent horizontally and inserted in bearings 24, integral preferably with the couplings 22. The bearings 24-. are cut away for part of their length to permit collars 25 to be mounted on the horizontal ends of the yokes 23 and secured thereon by set screws 26; V shaped supports 27 are journaled in bearings 28 on the collars 25 and have their free ends bent inwardly and inserted in suitable openings in the bars 1 and 2. I

A lever 29 is pivotally mounted intermediate its ends on the seat support 9 and is pro vided with the usual type of latch to engage with a toothed semi-circular rack 30 secured on the seat support 9. Bell cranks 31 and 32 are pivotally supported one above the other by a vertical pivot 33 on a casting 34 secured on the seat support 9; a link 35 is pivotally secured to the lever 29 above the pivot there of and extends forwardly, its forward end being bent into a hook which engages with a suitable perforation in an arm 36 projecting laterally from the bell crank 31 and preferably integral therewith; a similar link 37 is pivotally secured to the lower extremity of the lever 29 and extends forwardly to con nection with a laterally extendin arm 38 on the bell crank32 and extending in the same direction and parallel with the arm 36. 7

On the inner vertical portion of the yoke 23 is rigidly secured a member 38 having an eye in which is hooked an end of a link 39; the link 39 extends inward and is connected to a forwardly projecting arm to of the bell crank 31. A similar. member is rigidly secured on the inner, vertical portion of the yoke 23 and is provided with an eye in which is hooked an end of. a link 41 which extends inward and is connected to a forwardly projecting arm 42 of the bell crank 32.

Toraise and lower the gang beams, on which I have shown cultivating shovels of a well known type, I employ the following mechanism: The gang beams are arranged in pairs and each pair is vertically adjustable independently of the other, and by similar means, a description of the raising mechanism of one gang will suttice. Mounted in bearings 13 and AA on the frame bar 1 is a rock shaft 4L5 having rearwardly extending arms 16 and 47. A similar rock shaft 48 is journaled in a bearing 49, also mounted on the frame bar 1, and provided with rearwardly projecting arms 50 and 51. Mounted on the gang beams are brackets 52 to which are connected links 53 and 54 extending upwardly and pivotally attached to the arms 46 and 50 respectively. A lever 55 is rigidly secured to the arm 47 and a master lever 56 is rigidly secured to the arm 51; on the master lever 56 is a notched segment 57 with which a well known type of latch on the lever 55 is adapted to engage, and secured on the frame bars 1 and 2 is a notched segment 58 with which a latch on the master lever 56 is adapted to engage.

Connected to the links 53 and 5a near their lower ends are coiled balancing springs 59 which are also connected to the arms l6 and 50 of-th-e rock shafts 45 and 48 respectively. The links 53 and 54 are spaced apart by a yoke formed of members 60 and 61 pivotally connected to the links 53 and 54, and bent laterally to overlap, they are secured together by bolts or cotters inserted in suitable perforations in both members. In this mechanism just described it Will be seen that the outer gang beam can be raised independently of the inner gang beam by operation of the lever 55 after the latch thereon is disengaged from the segment 57, and it is also apparent that both gang beams can be raised simultaneously when the master lever 56 is freed from the segment 58 and operated, the lever 55 being held on the segment 57 on the master lever 56, or the inner gang beam can be raised independently of the other by disengaging both'lev-ers from their respective segments and operat ing the master lever 56.

As previously described the wheels 8 are supported on the axles so as to have their axis rearward of the main frame. This arrangement results in a very material advantage when the wheels are angled to right or left to change the direction of travel of the machine necessitated by unevenness of the rows of plants being cultivated, and this advantage consists in that when the wheels are angled the frame and the gang beams connected therewith are moved transversely of the machine toward the normal longitudinal vertical planes of the wheels, and

The operation of angling the wheels 8 and simultaneously imparting a lateral movement to the main frame and gang beams does not prevent independent lateral adjustment of the gang beams, for by actuation of the lever 29 forwardly the bell cranks 31 and 32 are operated by therods 35 and 37, and through the connection of the yokes 23 and'23 to the bell cranks 31 and 32 by the rods 39 and ll, the yokes 23 and 23 are moved toward each other to bring the gang beams, and cultivating devices thereon, closer together for close cultivation. A rearward actuation of the lever 29 will move the yokes 23 and 23 further apart carrying with them the gang beams and cultivating devices, as will be readily understood. When the lever 29 is in a vertical position, as shown in the drawings, the parts are in position for ordinary Cultivation, but rocking the lever 29 either way from the vertical adjusts the cultivating devices for rows of different distances apart, the gang beams swinging on the V shaped supports 27 by which they are supported on the' main frame.

The lateral movement of the main frame it is evident does not interfere in any way with proper adjustment-of the cultivating devices.
